In the dam foundation restraint area, mgo can be mixed into concrete to prevent dam longitudinal crack. research on autogenous volume change of rcc mixed with mgo, and research on thermal stress compensation of darn foundation prove that rcc mixed with mgo plays a role in dam crack control
在材料措施方面，深入研究高碾壓混凝土壩基礎約束區採用外摻mgo措施，利用其微膨脹性能補償壩體降溫過程中產生的溫度應力，以防止大壩縱向裂縫的發生。 -
In the program, the effect of lamination placement, construction interval, elastic modulus change, thermal insulation change, surrounding temperature change, concrete creep and autogenous volume change on thermal stress are considered. and such temperature control measurement as water pipe cooling, heat preservation of the dam surface, the pouring temperature control, the overflow across the dam top during flood season can also be simulated by numerical method
該程序在編制過程中考慮了混凝土分層澆築、施工間歇、彈模變化、絕熱溫升過程、環境溫度的變化、混凝土徐變、自生體積變形等因素對壩體溫度場及溫度應力場的影響，同時也考慮了水管冷卻、壩體表面保溫、控制澆築溫度、施工汛期壩頂面過水等各種溫控措施的數值模擬。 -
Temperature control and crack prevention of concrete - the simulation analysis characteristics of dams construction with mgo concrete, the theory apply " equivalent time " to the model for computing autogenous volumetric change of concrete which be relate to temperature history. it makes computing autogenous volumetric change of concrete be realized at case of arbitrary temperature history, so the problem puzzled engineer over a long period of time may be dispelled
針對溫控防裂的一項新技術?外摻mgo混凝土築壩技術的模擬計算特點，提出了應用「有效時間」理論，來考慮自生體積變形與溫度歷史有關的膨脹模型，使長期以來困繞工程界有關外摻mgo在任意溫度歷史下產生的膨脹變形的應力補償計算成為可能。
